Exploring the bio‐functional potential of polysaccharides from Morchella esculenta: A mini review

Food Biomacromolecules, EarlyView.
Abstract Polysaccharides, natural polymers of monosaccharides, exhibit diverse biological activities due to their molecular structures and functional properties. Morchella esculenta, a precious edible mushroom with higher market value, is also rich in polysaccharides (MEP) and holds potential as a bioactive compound with therapeutic and functional food

Isolation and Extraction of Gentian Polysaccharide and Its Protective Effect on Chemical Liver Injury

Food Safety and Health, EarlyView.
The water‐soluble polysaccharide GSBP‐N‐a‐1 with an average molecular weight of 3.82 kDa was successfully isolated and purified from Gentiana scabra. It was confirmed that the crude polysaccharides of Gentiana scabra could inhibit oxidative stress and inflammatory response by activating the Nrf2‐HO‐1 pathway, and significantly alleviate the chemical ...

Myelin Formation by Oligodendrocytes Is Enhanced Through Laminin‐411 and Its Derived Peptide

Glia, EarlyView.
Laminin (LM) α1, α2, and α4 chains are expressed at the myelination stage of oligodendrocyte (OL). LM411 and its E8 fragment enhance OL myelin membrane formation. A4G47 from LM411E8 is a novel peptide that promotes OL myelin formation. ABSTRACT In the central nervous system, oligodendrocytes (OLs) form myelin sheaths that accomplish the efficient ...

Polypept(o)ide‐Based Core–Shell Bottlebrush Polymers: A Versatile Platform for Drug Encapsulation

Macromolecular Bioscience, EarlyView.
This study developed polypept(o)ide‐based core–shell brushes (CSBs) with tunable sizes (Rh: 17–70 nm) for hydrophobic drug delivery. CSBs achieved 10% dasatinib loading through π–π interactions, enabling sustained release over 72 h. Notably, CSB‐dasatinib complexes showed comparable cell viability reduction to the free drug in U‐87 MG cells ...

Photoaffinity labeling coupled to MS to identify peptide biological partners: Secondary reactions, for better or for worse?

Mass Spectrometry Reviews, EarlyView.
Abstract Affinity photolabeling is a smart method to study noncovalent and transient interactions and provide a submolecular picture of the contacts between interacting partners. In this review, we will focus on the identification of peptide partners using photoaffinity labeling coupled to mass spectrometry in different contexts such as in vitro with a

Concentration‐Based Analysis of Metal‐Induced Tau Fibrillar versus non‐fibrillar Aggregation: Implications for Neurotoxicity in Alzheimer's Disease

ChemistryOpen, EarlyView.
Tau protein aggregation and fibrillation have been examined in relationship to three metal ions in this study. The research was conducted to see the effects of Zn2+, Cu2+ and Fe3+ ions at different concentrations on tau′s conformation, cytotoxicity in SH‐SY5Y cells, and free thiol levels.

Binding Differences of the Peptide‐Substrate–Binding Domain of Collagen Prolyl 4‐Hydroxylases I and II for Proline‐ and Hydroxyproline‐Rich Peptides

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Collagen prolyl 4‐hydroxylase (C‐P4H) catalyzes the 4‐hydroxylation of Y‐prolines of the XYG‐repeat of procollagen. C‐P4Hs are tetrameric α2β2 enzymes. The α‐subunit provides the N‐terminal dimerization domain, the middle peptide‐substrate–binding (PSB) domain, and the C‐terminal catalytic (CAT) domain.

Recent Advances in Enzymes and Chemoenzymatic Synthesis of Tetrasaccharide Linkage Region of Proteoglycans. [PDF]

Chembiochem
The tetrasaccharide linkage region of proteoglycans is synthesized through a series of well‐controlled enzymatic reactions in nature. The expression, activity, and substrate profile of these biosynthetic enzymes and the latest development of chemoenzymatic synthesis of linkage region‐bearing glycopeptides are summarized in this review.

Probing Enzymatic Acetylation Events in Real Time With NMR Spectroscopy: Insights Into Acyl‐Cofactor Dependent p300 Modification of Histone H4

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Lysine acylation is a rapidly expanding class of post‐translational modifications with largely unexplored functional roles; the study of acylations beyond acetylation is especially impeded by limited methods for their preparation, detection, and characterization in vitro. We previously reported a nuclear magnetic resonance (NMR)‐based approach

Pterostilbene Exhibits Broad‐Spectrum Antiviral Activity by Targeting the Enterovirus Capsid, Inactivating Viral Particles, Blocking Viral Binding, and Protecting Mice From Lethal EV‐A71 Challenge

Phytotherapy Research, EarlyView.
Pterostilbene (Pte) binds to the VP1 hydrophobic pocket of enteroviruses, stabilizing the viral capsid and preventing uncoating and RNA release. In vitro, Pte inactivates virions and impairs viral attachment, entry, and replication. In vivo, oral administration of Pte in hSCARB2‐transgenic mice reduces clinical symptoms and improves survival ...
